The present anchor bolt forming the subject matter of this specificationis made in detachable parts so that in case the uppermost part of the bolt becomes damaged it can be readily removed without any considerable loss of time and expenditure of labor in repairs.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which-- Figure 1 is a view of a part of the mortar 'aa i xo dhitg e dh d ia hab b l? 3 tipn, drawn upwardly the surface 16 of nt tlie amber 14 will interlock with the recess 15 of the key, thereby forming a secure attachment between the stem 9 and the socket 7. The upper end of the detachable stem 9 is threaded as at 17, so that when the key 13 is removed, the mortar 6 may be assembled in place on the to plane 5 of the foundation, and the detac able stem section 9 lowered through the perforations 6' in the mortar until they enter the open sockets 7 embedded in the foundation structure. The upper threaded portion 17 of the detachable stems 9 project sufiiciently above the mortar flange 6 to receive lock nuts 18, and as these are screwed firmly home they draw the bolt section 9 upwardly to embrace the key 13 when this has been inserted through the perforations in the socket member and .chamberll of the stem 9.
